Strange!
I’m getting same problem as Hameed’s loss of style.
Since I couldn’t import my solution as new release , I deleted the solution & imported as new solution using “Import” button. The solution worked fine.
Then I closed the servoy developer & opened it again. The strange thing here is all of my styles got deleted.
Also, I can’t create new style with old style name.
If I create new style with new name ,then it is not shown in editor & also in the form properties.
